Toma

A witch, who due to her vast powers, ended up bringing calamity to the witch world due to various factions fighting each other in order to take advantage of it. In order to stop the fighting, a seal was placed on Toma, putting her in stasis. It was a deed which she herself wanted ever since evil witches implanted the seeds of evil in her soul during the fighting, to prevent her soul from tainting completely. However, due to the strengths of her powers, the two sides of her soul gained form even without the body and began an endless struggle. It was during this struggle that Alice became caught in the middle. Alice though, realized that in truth, both sides were still of the same heart that just feared to truth itself, and freed Toma from her stasis.
In the end, the long stasis was able to give Toma the chance to gain control over her great magic, and with the command from the Grand Master, Toma ended up serving under Ateria.
